PCU – iLB – GPIO
There are 102 GPIOs available for use during the S0 ACPI state, and 44 are available 
for use from S5 to S0 (SUS). Most of these GPIOs can be used as legacy GPIOs through 
IO registers. This chapter describes their use as legacy GPIOs.

Signal Descriptions
See 
 for additional details.
The signal description table has the following headings:
Signal Name: The name of the signal/pin
Direction: The buffer direction can be either input, output, or I/O (bidirectional)
Type: The buffer type found in 
Description: A brief explanation of the signal’s function

Description
GPIO_S0_SC[101:0]
I/O
Varies
These GPIO pins are powered and active in S0 only. Many of 
these are multiplexed with other functions and may have 
different default pin names.
GPIO_S5[43:0]
I/O
Varies
These GPIO pins are powered and active in S5–S0 (SUS). Many 
of these are multiplexed with other functions and may have 
different default pin names. Some are used as straps.
